Technology acceptance research has tended to focus on instrumental beliefs such as perceived
usefulness and perceived ease of use as drivers of usage intentions, with technology characteristics as
major external stimuli. Behavioral sciences and individual psychology, however, suggest that social
influences and personal traits such as individual innovativeness are potentially important
determinants of adoption as well, and may be a more important element in potential adopters’
decisions. This paper models and tests these relationships in non-work settings among several latent
constructs such as intention to adopt wireless mobile technology, social influences, and personal
innovativeness. Structural equation analysis reveals strong causal relationships between the social
influences, personal innovativeness and the perceptual beliefs—usefulness and ease of use, which in
turn impact adoption intentions. The paper concludes with some important implications for both
theory research and implementation strategies.
